The macOS spell-checker was turned off. How do I turn it back on?

When you install Grammarly for Mac, the macOS spell-checker will be deactivated. This is intended to avoid any confusion and conflicting suggestions that could result from running Grammarly for Mac and the macOS spell-checker simultaneously. Deactivating the macOS spell-checker ensures that there is no mistaking the two when you’re using Grammarly.

If you’d prefer to have both of them active, you can reactivate the macOS spell-checker with the following steps:

  1. Open Finder and click Go
  2. Select Utilities and open Terminal.
  3. Paste the following command into the Terminal window, then press Enter:

    defaults write -g NSAllowContinuousSpellChecking -bool true

  4. Restart your computer for the change to take effect.
